How do I check more conditions in fluent validator

Question

0.00/5 (No votes)

See more:

I have a Model what contains a column "Confirmed" and "Details".

"Confirmed" can have a entry like "2024-01-11 21:10:42" or "NA". It should be valid if it has a DateTime and not valid by "NA".
"Details" can have "Delta", "Delta - ORT PAM", "Delta - Strasse_HNR2 PAM" or "ok". There it should be invalid, if it has "ok".

So all "NA" and "ok" can be removed before mapping to target model.

Sadly i'm getting that data from external in that form.

Is it possible to made rules for Fluent Validator for that?

What I have tried:

Read docs. But don't found anything that matches my needs. I just found "Otherwise" but as far i understand, i just have two possible checks.

Your first mistake, and it's a big one, is storing datetime values as strings. Your Confirmed column should be storing datetime values as DateTime types, which can also be null, not "NA".

Thats true. In that case i'm getting that from external and they writing a Date or "NA" in that field. They generating that information automatically.

Weird but OK. You can always use the .Must validator and supply your own custom code for converting the datetime string into an actual DateTime value. If that conversion fails, you move on to checking it for "NA", and if that fails, return false. If either condition works, return true.

Indeed it's weird. I think your idea is the best solution for this issue.

Update your question with sample code that you have tried. Use the green "improve question" link.

To be quite frank,there is more than enough information in the links provided for you to complete your task.

However, if you are expecting someone to write the code for you, without any attempt, then I recommend these websites:

Sometimes you can't come up with the simplest solutions. I don't have to validate every piece of information. In my case it is enough to exclude "ok" and "NA". That's enough to use .NotEmpty().NotEqual("ok") and .NotEmpty().NotEqual("NA").

Here is the official documentation: Built-in Validators — FluentValidation documentation[^] - has examples for each. Then for compound checks: Dependent Rules — FluentValidation documentation[^] - again with a sample.
